Make TCNPlus consistent, create the right config format, deleting assertion

[BiqianCheng]

• Ignore the changes of num_batches, which is somehow included in this commit
• Missing batch normalization in the FCNPlus json.file
• Ignore the modification of rnn.json
• ATTENTION starts from here In the src/models/get_model.py, the model name is selected to be "FCN" however it later refers to FCNPlus's configurations. To make this consistent, I request to change them all into FCNPlus.
• #25 The right configure format has been corrected. Otherwise, it will run into the "all strings cannot be converted to the right type" error.
• src/models/tsai/tsai/models/FCNPlus.py, the assertion doesn't make sense since layers=[128, 256, 128], kss=[7, 5, 3] in default. We will never be able to pass the assertion. I commented it out so it is possible to try the FCNPlus model and see its performance.
